I'm posting this for anyone who needs a good and emphasize Good quality Sub-woofer . I originally bout 4 MCM 55-2421 8" woofers ( incredible quality ) to build an transmission Horn sub cabinet but after really thinking about how big this would be in my little 12'x 13' room I decided to down size I built 2 really simple 11"x 15.5" x 22" ( outside) sealed w/ 3lb. of fiberglass insulation. These woofer have an Xmax of 16mm and move some big time air. If I were to use them in a bigger room I would definitely port them. But in this sealed cabinet they get down as low as 10Hz you feel the bass in your chest. I have these coupled to a 200w plate amp each.'

Sounds impressive. Over on HTS I have a thread called "Easiest DIY sub?" I think it is. It is simialr to my "bose cannon knock-off" here on diy. While I did not of course invent it, I have been rattling stuff for months now with a 12' (actually cut it to about 10 1/2') 12" dia. Sonotube + 12" sub driver with pretty impressive results. I claim a rarity in DIY speakers: "carpentry free" ... ongoing problem is how to mount the driver so that it doesn't come undone. Of course, having an unfinished huge tube in the living room is not to everyone's taste, but if you saw my living room you would not accuse me of having any

There both 8ohm speakers that are wired in series for 4 olms . they will rattle the walls if I turn bot units up to just 50 watts .They are only $ 29.00 they are going up steadily in price as they sell more of them as I only paid $24.00ea. 1 year ago....

My intended room is just about the same size with an 8 foot ceiling, it sounds like one of them might suit my needs. Or a pair housed in separate boxes.

Build just one box with 2 drivers this be all you will need and would easily suffice for room twice as large , I only built 2 cabinets just because I had the speakers ..... and they both can give you that earthquake feel all through your body. its an overkill for my little room and there easy on your budget....

Something to think about. The price sounds right for sure, more could go towards amplification. Speaking of which what are you powering and filtering them with? I'd like to get one of the Hypex plates with dsp but I'm pretty sure no one sells them over here.

I have Yung plate amps built in to them part # 301-508 @ Parts Express they handle all the crossover freq. Bass Freq's. do not need as much power to drive a woofer.... 200 watts is more than you really need inside of a home. Any more amplification is just going to drive the amp harder and a waist of money for home use as you would rarely if ever would crank it over 200 watts.
